when i was a kid In the 60's-70's I, collected 1000s of arrowheads from my fathers farm. I would tape the information to the artifact, the dilemma is all of the artifacts have been stained where the tape was applied to the arrowhead. How do I remove the stains without damaging the artifacts. Thanks, for any help Joe
Been there and done that! I had also used good ole elmers glue in my younger days. With just about any tape, the key is getting the adhesive warm enough to loosen and disolve away. I soaked my points in hot water (caution: but not scalding hot) and added a little grease cutting dish soap, and had great results. Do not however drop a cold point into boiling water, as it can magically burst into a hundred pieces. The hot water and soap worked well on the glue also. If any of your points have been in a cave environment (like many of mine), they may have encrusted deposits of calcified carbon ash. This is a very desireable characteristic to have present with authentications, as like patina bleaching it's pretty difficult to reproduce. So if this is present on any of your points, you may want to avoid laquer thinner or any other solvents that may contain hydrocarbons. These hydrocarbons tend to stay attached to the point, can show up under black light exams. Also, avoid trying to pick or scrath off any undesireable material with any pointed metal, that will also show up. Hope this helps and good luck!
Hi Joe, your already getting good information but in re-reading your original, maybe clarify and someone might have a cure. I read it to say remove STAINS not adhesives. Though flint is 8 on the hardness scale Im sometime surprised how porous some types can be. I've seen MANY points come out of moist soil looking knockout with colors and banding only to have them catch a dose of the BLAHS after washing and drying.
Bottom line I have no cureall suggestions for stains except experimenting with the likes of mineral spirits and the like on no value fragments....
Joe, I don't know how many points your dealing with, but it sounds like alot. Try one to start, soak for about 10 minutes in hot water, and lightly scrub with a plastic dish scrubber(do not use a brillo pad). I think you'll find that the adhesive stain left from the tape will come right off. I don't think it will be anything hard to do, and if the First one does well, then load up a big pot full and go for it!!
